Abstract (en)
The present disclosure relates to the field of memory technologies and provides a data sampling circuit, comprising a first sampling module configured to respond to a signal from the data signal terminal and a signal from the reference signal terminal and to act on the first node and the second node; a second sampling module configured to respond to a signal from the first node and a signal from the second node and to act on the third node and the fourth node; a latch module configured to input a high level to the first output terminal and input a low level to the second output terminal, or to input the low-level signal to the first output terminal and input the high-level signal to the second output terminal according to a signal from the third node and a signal from the fourth node; and an offset compensation module connected in parallel to the second sampling module and configured to compensate an offset voltage of the second sampling module. In this data sampling circuit, the second sampling module is additionally provided, and the offset compensation module is connected in parallel to the second sampling module, such that kickback noise is reduced.
